TSD: Move in some of the tcache fields.
...
We had put these in the tcache for cache optimization reasons. After the
previous diff, these no longer apply.

Move tsd link and in_hook after tcache.
...
This can lead to better cache utilization down the common paths where we don't
touch the link.

Hooks: Protect against reentrancy.
...
Previously, we made the user deal with this themselves, but that's not good
enough; if hooks may allocate, we should test the allocation pathways down
hooks. If we're doing that, we might as well actually implement the protection
for the user.

Hooks: Add a hook exhaustion test.
...
When we run out of space in which to store hooks, we should return EAGAIN from
the mallctl, but not otherwise misbehave.

Hooks: move the "extra" pointer into the hook_t itself.
...
This simplifies the mallctl call to install a hook, which should only take a
single argument.

Hooks: add an early-exit path for the common no-hook case.

Add "hook" module.
...
The hook module allows a low-reader-overhead way of finding hooks to invoke and
calling them.
For now, none of the allocation pathways are tied into the hooks; this will come
later.
